Private post disclosure via unchecked AJAX queries
Published Dec 31, 2025 · Updated Dec 31, 2025
Missing authorization in BdThemes Ultimate Post Kit before 4.0.16 allows remote attackers to read private and unpublished posts. Multiple AJAX load-more handlers, including upk_alex_grid_loadmore_posts, render attacker-selected posts without checking publication status. No authentication is required; the response exposes rendered HTML for content that WordPress otherwise keeps nonpublic.
